Following are examples of running tcl_stat.d on Tcl programs.
tcl_stat.d shows you the number of events per second that have happened since
the last line output. The default interval is 1 second, but you can specify
other intervals as arguments to the script.
This shows the sh_stat.d script reflecting the Code/Tcl/func_abc.tcl program.
